Sometimes we overcomplicate the Christian life by thinking that victory takes a long time to achieve. The reality is that Christ already won the victory, and we get the benefit of His victory in our life every time we yield to Him.
Don't overthink it - just yield to the Spirit of God in every little decision throughout the day, and resist the devil in the small stuff, and it will add up to the bigger victories. Walk and talk with God throughout the day. That's what victory looks like for the Christian.
"Submit yourselves therefore to God. Resist the devil, and he will flee from you." James 4:7
"But thanks be to God, which giveth us the victory through our Lord Jesus Christ." I Corinthians 15:57
"This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh." Galatians 5:16
"Trust in the LORD with all thine heart; and lean not unto thine own understanding. In *ALL* THY WAYS acknowledge him, and he shall direct thy paths." Proverbs 3:5-6 (emphasis mine)
